Question

我在我的heroku node.js应用程序中收到此错误。它运行正常，每当我们尝试访问应用程序时都会突然看到此错误，并且我们收到“内部服务器错误”。相同的node.js应用程序在我的本地运行正常。请让我知道如何解决此问题。与heroku支持一起发言，但他们无能为力。

Answer 1

在代码中的某处，您调用adaro的engine()函数而不提供file参数：

https://github.com/krakenjs/adaro/blob/467ec9aa8cc00a9326ed50cd3ca7fc3ac2b20ee3/lib/engine.js#L134

如果它在本地工作，请检查更新版本是否没有破坏express，dust，adaro等之间的相互兼容性：

rm -rf node_modules
npm install --quiet --production
npm start

最好在package.json（npm install --save --save-exact foobar）中设置固定版本。

我们无法解决此问题。与heroku支持团队交谈并被告知应该是应用程序问题。但我们的应用程序在本地开发环境中运行正常然后，我们在aws中部署了我们的应用程序，作为解决该问题的解决方法。
